| | Scuba Support - Eddy van Vliet will join the Doggersbank Expedition Dogger Bank, the largest sand bank in the North Sea
The Dogger Bank is a shallow, permanently flooded sandbar that separated the North Sea in the north and south. The bank extends over a length of 300 km from west to east and is located in the English, Dutch (in the northernmost tip of the Dutch Continental Shelf), German and Danish waters. Middle of the North Sea, the Dogger Bank is the largest sandbar in the North Sea. The Dogger Bank is between 18 and 30 meters deep, 2 to 3 times shallower than the surrounding area. The expedition focuses on the southwest (Dutch) part of the Dogger Bank.
Special habitats
The expedition will take to the southwestern part of the Dogger Bank. In this section, several distinct habitats:
1. Located deep muddy sections: In the southwest of the Dogger Bank are to be found deeper parts. The species in the deeper silty parts of the Dogger Bank the largest. The edges of the Dogger Bank in the present peat banks are an attractive habitat for unique species.
2. Shallow sandy bottom: Because tidal currents, wave action and strong currents caused by storms, there is intense water mixing allowing fine sediment and organic material is washed away. Its clarity and shallowness urges lot of sunlight on the shallow bottom. Several special shell species can be found here. Also, the Dogger one of the few areas in the North Sea where the stingray is relatively widespread.
3. Art Reefs -> hard substrate: On the Dogger Bank are several shipwrecks. These form a very special habitat at the Dogger Bank, where many hard substrate species.Because the environment of these wrecks includes sand, creates ecological islands of hard substrate in a sea of sand. Shipwrecks are not natural in origin, but as artificial reefs eventually taken over by many species and than become part of the ecosystem.
Within Natura 2000, various soil types of the first and second category described.Furthermore, natural shellfish reefs as important habitats, but not described as worthy of protection available on the Dogger Bank. Shipwrecks and subsequent animal species are not (yet) not to protect habitats within Natura 2000. The main reason is that samples from a research ship easier to take are of sandy soil or peat or a piece of hard substrate such as a wreck. About life on the wrecks on the Dogger Bank is little known.In the period before 1990, researchers from Bureau Waardenburg measured what the shipwrecks on the Dogger Bank grows. Thereafter, no further research done on the animal life on shipwrecks in the North Sea. Because shipwrecks have a large quantity of special types of inns, it is worthwhile to further investigate whether it would be necessary to include these habitats in Natura 2000.
